Hi Nandhu,

Bjørn is on the Christmas holiday.

Good to hear you find the solution. If you have further questions, please raise a new support case.

Nordic technical support staff will be reduced during the holiday season from 21st December to 7th January
Longer response time to tickets must be expected during this period.

Other DevZone users might be active and respond to public tickets as usual.

Merry Christmas & Happy new year.

-Amanda H

Bjron thanks for the reply

I find a solution and now i can able to debug with bootloder .

I made a small change in Application project setting in segger IDE.

Look the screen shot below.

Now when downloading file application.hex to nrf52832 using segger the Softdevice he is not loading with it .

so the issue of deleting bootloader section is sort out.

Bjron,

By referring the link you provided i changed the "uicr_bootlader_start_address" to 0x10001014 in flash_placement.xml .

and also included the "nrf_bootloader_write_bl_addr_to_mbr()" in main.c and called it in main().

But now the below error was showing,

Look the screen shot below

I take the memory layout of nrf52832 chip before and after flashing the "Application hex" with segger IDE .

BEFORE(ie now there is only SD+BL+BLS)

AFTER (ie now i flashed the application using segger ide)

Did you notice the variation in softdevice start address in both .

I think that while i programming through segger ide . BOOTLODER section which is overlapping with softdevice section is deleting . what's why i getting the "No bootloader was found " error.

Is there any solution for these.

[quote user="bjorn-spockeli"]Can you try to merge the bootloader hex with the settings hex and then merge the combined bootloader+settings hex with the SoftDevice? After flashing this combined bootloader+settings+softdevice hex, try to debug the application. [/quote]

bjron i did these same issue is showing again when i try to debug our Application using segger ide .

I will explain what i did

I merged the bootloader hex and bootloader setting hex and then i merged the Softdevice hex .Merged hex was attached below.

devzone.nordicsemi.com/.../SD_5F00_BL_5F00_BLS.hex

Then using nrf_Connect desktop application i programmed these hex to our custom board then the device started to advertise as "DfuTrag".
Then i open the application code in segger IDE and clicked on "Build and Debug" option the program was downloaded to the device successfully , but when i started the debug its showing above error i mentioned and the device is not advertising to.

thanks for the reply .

Please reply as soon as you can possible.

NOTE:- BOOTLODER HEX WE ARE USING IS NON DEBUG VERSION

Hi Nandhu,

There is a known issue in SDK v15.3.0, see https://devzone.nordicsemi.com/f/nordic-q-a/47651/uicr_mbr_params_page-and-uicr_bootloader_start_address-overwrite-the-beginning-of-the-softdevice.

Can you try to merge the bootloader hex with the settings hex and then merge the combined bootloader+settings hex with the SoftDevice? After flashing this combined bootloader+settings+softdevice hex, try to debug the application.

Best regards

Bjørn
